Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed March 28, 1914. Serial No. 827,905.

To all whom it may concern Be it known that 1, JAMES D. ELLIS, a citizen of the United States, residing at Santa Clara, in the county of Santa Clara and State of California, have invented a certain new and useful Device for Heating Water in Laundry-Trays, of which the following is a specification.

My invention relates to a device for heatin water in laundry trays and more particularly to that general class known as cement laundry trays.

The object of my invention is to provide a device for heating water and boiling the same in cement laundry trays, and also to provide a heating device for laundry trays of simple and durable construction, and to give thoroughly reliable service under all conditions.

A still further object of my invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a front elevation of laundry trays with heating plate in position. Fig. 2 is a left end elevation of laundry trays with heating plate in position. Fig. 3 is a plan view of laundry trays with heating plate in position. Fig. is a bottom plan view of laundry trays with heating plate and gas burner in place. Fig. 5 is a sectional view on line AA of Fig. 3. Fig. 6 is a sectional view on line BB of Fig. 3. Fig. 7 is a perspective detail showing the method of bending the upper edges of the heating plate which is embedded in the walls of the laundry tray.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference numerals.

The improved device for heating and boiling water in cement laundry trays forming the subject matter of the present invention comprises a copper plate 1 having upturned flanges 9. The upper edges of said upturned flanges 2 are cut in a distance and bent downward alternate as shown at 3, Fig. 7, and are embedded in the upright walls l of said cement laundry tray for the purpose of an anchor to copper plate 1 in said upright walls l, said copper plate 1 forming the bottom of the laundry tray. Fastened to plate 1 by a plurality of rivets 5 are guard plates 6, which may be made of any suitable metal of the required width and thickness. Connected to said guard plates is gas burner 7 and gas pipe 8 and controlling valve 9. This valve is for the purpose of controlling the required amount of gas to gas burner 7. Waste pipe connections are shown at 10 connected to the bot tom of copper plate 1 for the purpose of drawing off the water from laundry trays. Guard plates 6 surround burner 7 and are for the purpose of holding said gas burner in place under copper plate 1 and protecting the clothing of the operator when said gas burner 7 is in use.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a device for heating and boiling water in cement laundry trays, the combination of a cement tray having walls, a copper plate having upturned flanges thereon, the upper edges of said flanges cut inward a distance and bent downward alternate, adapted to engage within the upright walls of said cement laundry tray forming an anchor to said copper plate, said copper plate forming the bottom of said cement laundry tray, guard plates fastened to said copper plate, a gas burner connected to said guard plates, means by which said gas burner is connected to a gas pipe and means by which the gas is controlled to said gas burner, as shown and described.

2. In a device for heating and boiling water in cement laundry trays, the combination of a copper plate forming the bottom of the cement laundry tray, said copper plate having upturned flanges thereon, the upper edges of said flanges cut inward a distance and bent downward a distance alternate adapted to engage within the upright walls of said cement laundry tray forming an anchor to said copper plate, guard plates and means of fastening the same to said copper plate, a gas burner and means of fastening the same to said guard name to this specification in presence ef two plates, means by which gas is fed and consubscribing Witnesses. trolled to said gas burner, means by which the Water is drawn out of said laundry JAMES ELLIS' trays, said guard plates surrounding said Witnesses: gas burner, as and for the purpose described.
